scope:

This standard establishes interface and associated verification requirements for the control of the electromagnetic interference (emission and susceptibility) characteristics of electronic, electrical, and electromechanical equipment and subsystems designed or procured for use by activities and agencies of the Department of Defense. Such equipment and subsystems may be used independently or as an integral part of other subsystems or systems. This standard is best suited for items that have the following features: electronic enclosures that are no larger than an equipment rack, electrical interconnections that are discrete wiring harnesses between enclosures, and electrical power input derived from prime power sources. This standard should not be directly applied to items such as modules located inside electronic enclosures or entire platforms. The principles in this standard may be useful as a basis for developing suitable requirements for those applications. Data item requirements are also included.

The applicability of the emission and susceptibility requirements is dependent upon the types of equipment or subsystems and their intended installations as specified herein.

Application-specific environmental criteria may be derived from operational and engineering analyses on equipment or subsystems being procured for use in specific systems or platforms. When analyses reveal that the requirements in this standard are not appropriate for that procurement, the requirements may be tailored and incorporated into the request-for-proposal, specification, contract, order, and so forth. The test procedures contained in this document shall be adapted by the testing activity for each application. The adapted test procedures shall be documented in the Electromagnetic Interference Test Procedures (EMITP)(See 6.3).

The standard has two primary sections, the main body and the appendix. The main body contains the interface and verification requirements of this standard. The appendix is non-contractual and provides rationale for the requirements and guidance on their interpretation and use. The paragraph numbering scheme for the appendix parallels the numbering for the main body requirements except that an extra "0" digit is included (for example, 20.0 rather than 2.0). Occasionally, there are references in the main body to appendix material where an obvious need exists for the appendix information to be examined.

The emissions and susceptibility and associated test procedure requirements in this standard are designated in accordance with an alphanumeric coding system. Each requirement is identified by a two letter combination followed by a three digit number. The number is for reference purposes only. The meaning of the individual letters is as follows:

C = Conducted

R = Radiated

E = Emission

S = Susceptibility

a. Conducted emissions requirements are designated by "CE---."

b. Radiated emissions requirements are designated by "RE---."

c. Conducted susceptibility requirements are designated by "CS---."

d. Radiated susceptibility requirements are designated by "RS---."

e. "---" = numerical order of requirement from 101 to 199.

intended Use:

This standard is intended for use in the acquisition cycle of equipment and subsystems to specify the electromagnetic emission and susceptibility requirements for the control of EMI.
